190435-93-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 190435-93-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,4,3 and 5 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 190435-93:
(8*1)+(7*9)+(6*0)+(5*4)+(4*3)+(3*5)+(2*9)+(1*3)=139
139 % 10 = 9
So 190435-93-9 is a valid CAS Registry Number.

Chemical selection and self-assembly in a cyclization reaction
Rudkevich,Rebek J.
, p. 846 - 848 (2007/10/03)
Self-help: A reaction product recognizes a stable intermediate and channels its reactivity to the formation of an eleven-membered ring (see below). A template effect is proposed, which involves molecular recognition through hydrogen bonding. PFP = pentafl
